FUNCTIONAL DESCRIPTION
The LS151 is a logical implementation of a single pole,
8-position switch with the switch position controlled by the
state of three Select inputs, S0, S1, S2. Both assertion and
negation outputs are provided. The Enable input (E) is active
LOW. When it is not activated, the negation output is HIGH
and the assertion output is LOW regardless of all other
inputs. The logic function provided at the output is:
Z = E (I0 S0 S1 S2 + I1 S0 S1 S2 + I2 S0 S1 S2
+ I3 S0 S1 S2 + I4 S0 S1 S2 + I5 S0 S1 S2 + I6
S0 S1 S2 + I7 S0 S1 S2).
The LS151 provides the ability, in one package, to select
from eight sources of data or control information. By proper
manipulation of the inputs, the LS151 can provide any logic
function of four variables and its negation.
